Study on Genetic Diversity of Phellodendron amurense based on cpDNA

In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity haplotype 0.43×10 -3 0.41, respectively at the level species. The AMOVA revealed that only 8.53% variation was explained by differences among geographical groups, whereas inter-population intrapopulation 18.32% 71.35% variation, respectively. Phylogeographical relationships showed all clustered into lineages. Haplotype H1 H2 cluster together, H3 composed a group. TCS network located center lineage, it appears to be an ancestral haplotype. So we hypothesized Northeast China North had common origin. mismatch distribution species suggested not undergone recent expansion, but expansion. results consistent with Tajima’s D Fu’s Li’s test.
